Remove all the netinstall software from the initrd

Don't put all the netinstall stuff in the initrd. Should probably make
the initrd a lot smaller and we might get to have a single initrd for
both i486 and i686 kernels.
Remove the netinstall options from SeTmedia

Keep a SeTmedia-net file that includes these options as a backup, in
case we want to use it for a super slim iso in the future.

Make it possible to have core-only or core/basic-only installations

If only a "core" directory is found in the installation medium, don't
offer and options about installation mode, just default to "CORE". If a
"full" directory is not found in the installation medium, offer the
option between "CORE" and "BASIC" only. Offer all option only if a
"full" directory is there.
